script

When 'Script' execution mode is set this value contains the entire
python script as a single string (not the script name as you might
expect) which can be modified to run different scripts.

When 'Module' execution mode is set this value will contain a single
line string - module name and function "module.func" or
"package.modile.func" where the module names are python
textblocks or external scripts. note: once this is set the script
name given for warnings will remain unchanged.
